Jul 15, 2023 · What Are the Symptoms of Sodium Nitrite Toxicity? It’s important to know about the signs of sodium nitrite poisoning. If you think someone took it, look for the symptoms of methemoglobinemia.
Symptoms of nitrate poisoning can vary depending on the amount and duration of the exposure. Those with very mild methemoglobinemia might not have any symptoms at all, or might appear a little pale and feel tired.

This article is about the safety of sodium nitrate, a common preservative used in cured meat products. It explains how nitrates and nitrites serve an important bodily function and are found in vegetables as well as processed meats. The article also discusses the potential dangers of nitrosamines, which can be formed from sodium nitrate, and compare...
Sodium nitrate is a common preservative used in cured meat products, linked to heart disease and diabetes. The human body needs nitrates and nitrites which serve an important bodily function. Most of our nitrates come from vegetables.
85% of the nitrates in our diet come from vegetables, most notably celery, spinach and carrots. These provide the body with healthy carbs and fiber that help prevent conversion of nitrosamines into carcinogens.
The amount of sodium nitrate allowed in cured meat products varies depending on the type of meat but has strict limits set by USDA (e.g., bacon 120 ppm). Celery powder doesn't have these limits as it's not regulated like chemically processed sodium nitrates are by USDA; its residue is about 10 times higher than traditionally cured products'.
Acute acquired methemoglobinemia is the most important adverse health effect caused by excessive nitrate/nitrite exposure. The known toxic effects from nitrate exposure result from the conversion of nitrate to nitrite.
Clinical manifestations can include cyanosis, hypoxia, altered consciousness, dysrhythmias, and death. The majority of reports on sodium nitrite poisonings have been the result of unintentional exposures. We report a case of an intentional fatal overdose of sodium nitrite.
